Zhu YY, et al. - Researchers assessed the morbidity and mortality related to bilateral internal mammary artery (BIMA) use vs single internal mammary artery (SIMA) use in a propensity-matched cohort of patients. During the study period, 3,594 consecutive patients underwent coronary artery bypass surgery. A total of 29% of procedures were performed off pump, and a greater proportion were in the BIMA group (43% vs 21%). BIMA vs SIMA use was shown to be related to similar rates of deep sternal wound infection, with the majority being superficial infections that did not lead to increased mortality or transfusion needs. More consideration should be given for the use of BIMA in coronary artery bypass surgery.
